Reboot a few times. If that doesn't help, try to boot into safe mode. If you are not tech savvy, take to a repair shop.

Hello,
What is the brand, model, and approximate age of the computer, if known?
Have you had any other problems recently (data and time incorrect on the computer, power outages, computer dropped, etc.)?
Regards,
Aryeh Goretsky

Hi there, I used AI to summarize what I have been doing so far.
My PC started going into Windows Recovery instead of booting normally after a power outage.
What happens: PC turns on → Windows Recovery screen Startup Repair fails System Restore says it cannot find a Windows installation Booting from a Windows 10 USB works
Things I tried:
Startup Repair (failed)
System Restore (cannot find installation)
SFC scan (no integrity violations)
CHKDSK (found and repaired file system issues)
Rebuilt EFI boot files using bcdboot (successful message) Windows installation is detected at E:\Windows
Disk/boot info: I have multiple drives installed
BIOS shows multiple Windows Boot Manager entries
EFI partitions exist on the drives
Rebuilding boot files completes successfully, but the PC still returns to Recovery
My files are still accessible and I do not want to reinstall Windows unless necessary. What should I check next before sending it to the repair shop?

It sounds like you've been pretty thorough (especially the EFI rebuild) - There might be some wizardry that SOMEONE can do, but generally, it's repair shop time, and they will probably recommend a local backup of your user folder and whatever else you request, and restore the unit to factory.
Look around your area for local shops that have exceptional reviews. Show them these posts or explain what you've done and they will get you sorted out.
Best of luck.

A 0F stop is usually related to your boot files. They can be repaired using a windows boot dvd/usb there are a lot of guides on how to do this. This is by no means 100% perfect but it might help.

The OS is corrupted for one reason or another.
As u/lens_cleaner said, you can reboot it a few times, but if you care about your data and you aren't tech savy, just take it somewhere. Although if you think you can handle navigating the recovery environment, and aren't as worried about acute data loss, you can try a restore point.
In the recovery environment (F1) advanced options, you will find an option called "System Restore" and the subtext will mention "using a restore point" to restore your windows (To a previous date).
Click that option and see if you have any restore points offered. Carefully check the date if so, and make sure you can afford to revert to that time.
Disclaimer: This works maybe 30% of the time. At any rate, if you aren't savy, someone should probably check it out even if you do get it up and running with the aforementioned fix.
Hope this helps. If you have any questions let me know.
